Go in real-time safety critical applications
summary
Claim: a garbage collected language (Go) proves viable for mechanical real‑time safety‑critical systems when running on a Linux SBC and careful design. Tools actually used: Go on Linux, TinyGo for microcontrollers, LLVM, and the Go runtime/GC. Measured wins: CPU drops from 60% CPU on four cores to 5% on one core, sampling improves 300 to 1000 samples per channel, and 50 tests including 10 live fires show zero software failures while exposing hardware faults. Limitation: TinyGo is promising but not yet suitable for hard real‑time safety‑critical control.
